Specification of Letters Patent.

Patented Oct. 5, 1909.

Application filed April 12, 1909. Seriallio. 489,401.

To all whom it may concern:

Be it known that- I, JOSEPH A, WEST, a citizen of the United States, residin at Miertown, in thecounty of Grant and me of Indiana, have invented a new and useful Paint, of which thefollowing is a specification. v

It is the object of the present invention to provide a paint designed chiefly for 'use in painting bridges, roofs, and like structures which are exposed to the elements and which will effectually protect the structure cfrom the elements.

The invention further aims to provide a paint of the character stated which, when it dries, will not be brittle but on the other hand will be 'flexible and elastic to such degree as to positively insure against chipping. J

The paint embodying the invention is of and iron structures against rust, and it is one object of the present invention to embody in the composition of thepaint, a substance which will impart thereto a metallic luster and color or appearance without detracting from the water-proof properties of the paint.

In compounding the aint embodying the presentinvention, the ollowi'ng ingredients are intimately mixed in the proportions Coal-tar 1 barrel. -()xid of iron 15 pounds. Slate -15 pounds. Chipped rubber 20 pounds. Asbestos"; 10 pounds. Gasolene 5 gallons. Asphaltuni 5 gallons. Cement pounds. Turpentine"; 5 gallons.

After these ingredients have been thoroughly mixed, .the mixture .is thinned to the required fluidity by the addition thereto of a sufficient quantlty of gasolene, this quantityv being of course added in addition to that introduced at the time of mixing the ingredients. It will be understood of course that the 'oxid of iron employed in compounding the paint is the ferric oxid commonly known as ocher and that this ,ingredient serves the purpose of a pigment,

the slate, which prior to mixing with the other ingredients, is ground to a fine powder, being also incorporated to impart the I required color to the finished product, this .ingredient further imparting a glazed appearance-to the paint when applied and dry.

The coal tar renders the paint water-proof and also imparts thereto a certain degree of flexibility and elasticity which, owing to its admixture with certain other of the ingredients of the compound, is retained or apparent even after the paint has dried although only to such degree as will effectually obviate cracking or chipping of the paint. The chipped rubber, preferably in the nature of granules, also imparts flexibility and elasticity to the finished product and the asbestos to a certain de ree rendersthe structure upon which the palnt is applied fire-proof and being of a fibrous nature, acts as a binder whereby to hold the particles of rubber, cement, and slate, in a state of combination.

The asbestos furthermore, while acting as a binder and also serving the useful function of a fire-proofing ingredient, if anything, adds to the flexibility of the paint and renders the same less liable to crack and chip, owing chiefly to its fibrous nature.

The Y ga'solene employed of course acts as a solvent and also as a-quick drier for the paint in addition to rendering the paint snfiiclently fluid for application to a structure,.and the asphaltum adds to'the water-proof properties of the paint while the turpentine 1s provided asa vehicle and also to retard the drying of the paint tothe proper degree. .e cement ofcourse possesses substantially the same properties as the slate.

From the foregoing description of the applied in the samemanner as any ordinary paint and .shouldit becometoo inspissated foruse, it may be readily thinned by the addition of gasolene. It will be understood, of course, that in place of the oxid of iron and the slate, other pigment may beequally as well employed although these pigments are paint embodied in the present invention, it

paint will not become hard and brittle preferable in that they will impart to the paint a metallic or slate-like appearance'and are well adapted to withstand the elements.

What is claimed is 5 A paint embodying in its composition coal tar, oxid of iron, slate, chipped rubber, asbestos, gasolene, asphaltum, cement, and turpentine in about the roportions of coal tar one barrel, oxid of iron fifteen pounds, slate, 10 fifteen pounds, chipped rubber, twenty pounds, asbestos, ten pounds, gasolene, five gallons, asphaltum, five gallons, cement, fifty 7 pounds, and turpentine, five gallons.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature 15 in the presence of two witnesses.

JOSEPH A. WEST.
